A Brief Study of Methods to Determine the Electrical Resistivity of Materials

<p class="Abstract">Present study deals with the of methods to calculate resistivity materials. Different are discussed which determine specific materials on basis their shapes and sizes. Their working, structure, advantages loopholes in a brief manner. Materials categorized according magnitude resistivity. The two probe method is helpful measuring high resistive samples while four can be used for low resistance. Pulse measures having small physical dimensions. Montgomery useful finding individual resistivities anisotropic materials.</p>
